Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Liquid boils at a lower temperature at the top of a mountain than at sea level.
This is because the pressure at the top of a mountain is low. As the pressure is lowered, the boiling point is lowered. In other words, the boiling point is directly proportional to the pressure.
Thus both Assertion and Reason are correct and Reason is the correct explanation for Assertion
